Short answer. As a rule, no. The Rules of Court allow any party to appeal a judgment unless the accused will be placed in double jeopardy — and an appeal from an acquittal that seeks to re-litigate the accused's guilt does exactly that. A verdict of acquittal is, for the prosecution, effectively final.
What the law says
Any party may appeal from a judgment or final order, unless the accused will be placed in double jeopardy.

The rule is broad — with one carve-out
The provision on who may appeal is strikingly short: Any party may appeal from a judgment or final order, unless the accused will be placed in double jeopardy. Notice its structure. The right to appeal is given to any party — the accused, the prosecution, even the offended party in a proper case. There is a single limit, and it is not about who is appealing but about what the appeal would do to the accused. If entertaining the appeal would place the accused in double jeopardy, the appeal is barred, whoever brings it.
Why an acquittal shuts the door
Double jeopardy is the guarantee that a person who has been put on trial for an offense and acquitted cannot be made to answer for the same offense again. An appeal by the prosecution asking a higher court to review the evidence and convict is, in substance, a second attempt at conviction for the same offense — precisely what the guarantee forbids. That is why the bar operates almost exclusively against the prosecution. The protection deliberately runs one way: an accused who is convicted may appeal and take the risk of the review, but an accused who is acquitted is entitled to rest on that verdict.
What the wording does — and does not — prohibit
Read the carve-out precisely: the appeal is barred unless the accused will be placed in double jeopardy. The rule does not say the prosecution may never come to a higher court; it says no party may pursue a review that exposes the accused to a second jeopardy for the same offense. Whether a particular challenge crosses that line — for example, one that does not ask the court to revisit the finding on guilt at all — is a technical question that turns on exactly what is being questioned and how. That assessment is where a lawyer's judgment is indispensable.
If you are the offended party
Private complainants often feel an acquittal is the end of everything, and it is important to understand what actually became final: the criminal verdict on the accused's guilt. If you are considering any challenge, move quickly — obtain a certified copy of the judgment, note the date you or your counsel received it, and bring the record to a lawyer at once, because the time for any post-judgment step is short and strictly counted. What you should not expect is a simple appeal that asks an appellate court to declare the acquitted person guilty; the double jeopardy bar stands squarely in the way of that.
